PERFORATlNG-STAMP.

SPECIFICATION forming part of Letters Patent No. 379,271, dated March 13, 1888.

Application filed February .21, 1887. Serial No. 228,313. (No model.)

To all 1072 0112, it may concern.-

Be it known that we, NILs ENGLUND and OLOF OHLSON, both of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Perforating Stamps, of which the following is a specification.

Our invention relates to that class of perforating-stamps used more especially for perforating checks, which punch or pierce the paper, so as to prevent the alteration of the check, draft, or note.

Ourinvention is designed to punch or pierce in the check the amountthereof as expressed in words arranged in a straight line, and for that purpose is provided with an automatic feed so arranged as that after the punching of each word the paper will be fed just enough to present aclear space for the next word with a uniform spacing between the words.

Our invention consists in the parts in com bination, hereinafter describedand claimed.

In the drawings, Figure 1 is a side, Fig. 2 a plan, (both partly in section,) and Fig. 3 a front View, of our machine. Fig. 4 is a cross-section on the line a: m, Fig. 1. Fig. 5 is a vertical section. Fig. 6 is an enlarged section of the die and punches, and Fig. 7 shows the appearance of the letters which we prefer to employ and which are produced by the punches and dies shown in Fig. 6.

A is the frame of the machine, shaped somewhat like the letter G, through which pass the shafts B and C, said shafts having keyed at one end the equal gears D F, meshing with each other, and at the other end the flanged disks E G.

Referring, now, to Fig. 5, it will be seen that the disk E has a flange, e, at some distance from its edge. In the space between the flange e and the edge of the disk E is fastened the punching mechanism, consisting of a guide and clearer,f, and the puuchplungera, having a stem, d, guided by brackets b and flange e, which is pierced for that purpose. Pins mm around the disk E are for the purpose of steadying the brackets 71 b. Surrounding the stem (1 is a spring, 0, abutting against the bracket Z) and the collar h, secured to stem d.

Within the flange e is a boss, II, fitting over the hub of disk E, or over the shaft B, which may revolve in the boss U. The latter is held in place by a screw, is, projecting into an annular groove in the shaft 13 or in the hub of the disk E. In the boss U slides a plunger,V, actuated by a lever, W, and connection V,'the fulcrum of theleverW being at X. The punchplunger a, the guidef, and the flangeg of disk G have a series of corresponding holes forming the outlines of the letters of the word desired, and the punch-plunger ahas secured in these holes a series of punches, (marked 1,) for which the corresponding holes in the flange g form dies.

In the drawings but one plunger-head a, with its appurtenances, is shown; but it is to be understood that as many of them are to be ranged around the disk E as are necessary to include all the desired words, and figures, also, if it be desired to use them. Each plunger, of course, contains a single word.

All the plungers are duplicates of that shown in detail in Fig. 6, except that the punches are arranged in different outlines to produce the various words required. The spacing or arrangement around the disk E of the punchplu ngers is merely one of convenience, depending on the number of words, 85c, used. If spaced, as indicated, by the pins m, Fig. 3, provision is had for any amount up to a million.

H is a hand-wheel on the shaft 0, used for turning the disk, so as to bring the proper punches and corresponding dies into action. To bring the disks accurately into position after they have been placed approximately by hand, the pin 2', having a pointed end, is attached to the lever TV, so that on the depression of the lever the pin z enters a hole, j, in the edge of disk E. c

Having described the punching devices, we proceed to the feeding devices.

Sliding in guides at 0 on the table I is a plate, K, to which is pivoted the paper-clip J. Attached to the plate K at its front end is the rackbar L. The back end of the rack-bar L is guided by the piece 1), which projects from the table I through a slot (aide Figs. 1 and 2) cut in the plate K nearly from end to end. Surrounding the rack-bar L for a portion of its length is a spiral spring, M,which is itself surrounded by a tube, N, slotted below, and outside of all is the guide 0, secured to the table I. The front end of the spring M abuts against the tube N and the back end against the piece 19. (Vide Fig. l.) The shaft X, which is secured to and forms the fulcrum of lever W, has affixed to it the flexible arm Y, which extends to the lug Z, attached to the tube N.

R, Figs. 1 and 3, is an arm projecting through a slot in the table I from the tube N, and carrying at'its lower end the finger S. In line with the fingerS is one of aseries ofgraduated studs or stops, T, the purpose of which will be explained when describing the opera tion. The pawl P is attached to the tube N and engages ,in the teeth of the rack-bar L. In front of the pawl I is another pawl, Q, fixed to the table I and inclined in the opposite direction to the pawl P. The spring of pawl Q holds it out of contact with the rackbar L, except when the advance of the pawl P presses down the pawl Q, when it stops both the pawl P and the rack-bar L. A lug or pin may be substituted for the pawl Q if the plate K be made to move with so much friction as to render it not liable to move farther than it is impelled by the spring M and pawl P.

The operation is as follows: The check is held by its top edgein the clip J,thcpawl P is raised, and the clip J, with its attached plate K and rack-bar L,is slid back till thecheck is in proper position for receiving the first word. At this time the tubeNis pressed forward by the spring Mas far as the stop or pawl Q will allow, the lever WV being fully raised. The disksEG are turned till the proper word is in position. The handle W is then depressed, and the pin 2' enters the hole j, so as to bring the disks ac curately into position. The further depression of the handle drives the punches through the paper by the action of the plunger V on the stem (1. The depression of the handle \V also revolves the shaft X, and, through the arm Y, drives back the tube N until the finger S,connected to the tube,strikes the stud T, after which the arm Y yields if the handle \V be further depressed.

It is obvious that the punchinglever must descend an equal amount each time, while the feeding device will be stopped at varying points by the graduated stops. The connection Y must therefore be yielding.

On raising the handle \V the spring 0 raises the punches Z, and the spring M impels the tube N forward, carrying with it the rack-bar L, the plate K, and the clip J, thus feeding the paper forward in readiness for the next word. The amount that the paper is fed varics with the length of the word just punched. The tube N is always stopped at the same point by the pawl or stop Q, so that the distance it feeds the paper forward depends upon the distance it is carried back by the arm Y.

This distance is regulated by the space between the finger S and the stud T, so'that by providing studs T, &c., of varying lengths around the disk G, which will be in turn brought opposite the lingo rS as different words are brought in position for punching, a variable feed is produced corresponding to the varying lengths of the words punched.

It is plain that the location of studs T in the disk G rather than in disk E is a matter of convenience only, the arm and finger R S being more out of the way and the disk G being less filled up than the disk E, with its punches, 85c. Ve may employ needle-pointed punches,which need no die or matrix, in which case the lower disk, .G, may be dispensed with by putting stops T on the disk E.

The essential parts of our complete device consist of adisk or disks having ranged about the circumference stamps or punches to form the words or figures desired and having a series of stops of varying length, a clip for holding the check and a device for feeding the clip, said device being actuated by an elastic connection with the punching-lever and limited in its movement by a fixed stop at one end of its stroke and by the graduated stops upon the disk at the other end of its stroke.

1. The combination of disks connected to rotate together, one carrying punches, the other carrying dies, and having a series of graduated stops, a clip for holding the check, a rack and pawl for feeding the clip, a spring impelling the pawl in one direction to a fixed stop, an elastic connection to the punch-actuating device moving the pawl in the other direction, anda finger carried by the clip coacting with the graduated stops, substantially as and for the purpose described.

2. In a perforating-stamp, the combination of a clip, a projection or finger attached to the clip, graduatedstops coacting with said finger, and an elastic connection between said clip and the punching mechanism, substantially as shown and described.

3. In a perforating-stainp, the device for giving an automatically-varied feed,consisting of graduated stops T, finger S, arm R, pawl P on tube N, inclosing spring M, and rackbar L, attached to paper-clip J through plate K, and connected by spring'arm Y to handlever \V, all combined substantially as described.
